Description
DC/DC power module DC/DC conversion is to convert the variable DC voltage into a fixed and stable DC voltage, also known as DC chopper. There are two ways of working the chopper, one is the pulse width modulation mode Ts unchanged, change ton(universal), and the other is frequency modulation (1)Buck circuit - buck chopper, the output average voltage U0 is less than the input voltage Ui, the polarity is the same. (2)Boost circuit - boost chopper, the output average voltage U0 is greater than the input voltage Ui, the polarity is the same. (3)Buck-Boost circuit - Buck or Boost chopper, the output average voltage U0 is greater than or less than the input voltage Ui, the polarity is opposite, inductive transmission. (4)Cuk circuit - buck or boost chopper, the output average voltage U0 is greater than or less than the input voltage Ui, the polarity is opposite, capacitive transmission. There are also Sepic and Zeta circuits. The above is a non-isolated DC-DC converter circuit, and the isolated DC-DC converter has forward circuit, flyback circuit, half-bridge circuit, full-bridge circuit and push-pull circuit.
